The anchor that never moves
The West African CFA franc does not trade freely on global markets. Instead, it is pegged by law to the euro at a permanent rate of 655.957 CFA francs per euro, meaning 1 euro buys 655.96 today. If you pull up a long-term EUR/XOF chart, you'll see a virtually flat line: the pair has moved 0.0% over the past year, 0.0% over 5 years, and 0.0% since December 2008.
Checking the live EUR/XOF rate reveals an annualized 12-month volatility of just 1.7%, reflecting slight mid-market spreads rather than real currency shifts. While currencies across Africa have suffered double-digit depreciations in recent years, an expatriate sending money from Paris or a merchant booking a 65,595.70 XOF shipment in Dakar faces zero nominal currency risk against the euro.
This arrangement governs 8 sovereign nations in the West African Economic and Monetary Union (UEMOA): Benin, Burkina Faso, Côte d'Ivoire, Guinea-Bissau, Mali, Niger, Senegal, and Togo. A companion currency, the Central African CFA franc (XAF), binds 6 other central African nations under a matching peg. Together, they represent one of the world's longest-lasting fixed exchange rate regimes.
How the French Treasury guarantee works
A fixed exchange rate cannot survive on promises alone. Most pegged currencies rely on massive foreign exchange reserves to defend their target. The CFA franc operates differently: its convertibility is backstopped directly by the French Treasury, not France's central bank.
Under the monetary cooperation agreements, France promised to supply unlimited French francs (and later euros) if member states ran out of foreign currency to maintain the peg. This guarantee transitioned from the franc to the euro in 1999. In exchange for this overdraft facility, the regional central bank, the BCEAO, historically had to deposit a substantial share of its foreign reserves into an "operations account" held at the French Treasury in Paris. French officials also sat on the BCEAO's governing boards.
This mechanism originated on December 26, 1945, when France created the currency across its colonies as the Franc des Colonies Françaises d'Afrique. Following independence in the 1960s, the name was recast to the Franc de la Communauté Financière Africaine. The institutional architecture remained largely intact for decades, anchoring domestic monetary policy to France and eventually to the European Central Bank in Frankfurt.

What happens when the dollar moves
The euro peg provides domestic price stability against European goods, but it creates a blind spot. West African economies trade heavily in commodities priced in US dollars: crude oil, cocoa, gold, cotton, and refined fuels. Because the CFA franc is tethered to Frankfurt, it rides every wave of the euro-dollar exchange rate.
When the US dollar strengthens against the euro, the CFA franc automatically weakens against the dollar, whether local economic conditions justify it or not. Today, 1 dollar buys 585.83 CFA francs, compared to 434.78 (Nov 26, 2009) at its lowest point in late 2009. Over the past 12 months alone, USD/XOF has swung between 546.98 (Jan 28, 2026) and 589.79 (Oct 28, 2026), registering an annualized volatility of 4.8%.
A stronger greenback pushes up local fuel and fertilizer import bills across West Africa. When a port authority in Abidjan or a transport company in Bamako settles an invoice of 58,582.89 XOF, currency depreciation against the dollar can fuel domestic inflation even though the rate against the euro remains frozen. You can see this dynamic in our guide on who wins and loses with a strong dollar.
The trauma of the 1994 devaluation
A peg can offer years of calm, but if structural imbalances widen, the reckoning can be severe. In the late 1980s and early 1990s, world prices for cocoa and coffee collapsed. At the same time, the French franc appreciated, dragging the CFA franc up with it and making West African exports uncompetitive.
With fiscal deficits mounting and reserves dwindling, France and the International Monetary Fund concluded that the peg was unsustainable. On January 12, 1994, leaders gathered in Dakar and announced an overnight devaluation that cut the currency's external value in half. The parity was abruptly halved, doubling the local cost of French currency.
The move triggered sudden price shocks across the region. The cost of imported medicine, wheat, milk, and machinery doubled by morning. While the devaluation eventually restored export competitiveness, it wiped out middle-class savings and left deep scars. Understanding what currency devaluation means remains a living memory for millions of West Africans, shaping the intense public caution around dismantling the peg today.
Stability versus sovereignty
The CFA franc divides economists and citizens like few other monetary systems. The case in favor rests on inflation control. While neighboring economies like Nigeria have suffered sharp currency drops and high inflation (examined in our look at the Nigerian naira's fall), the UEMOA zone has historically enjoyed lower, more predictable consumer price growth.
Regional trade is frictionless between member states, and international investors face minimal convertibility risk when lending in euros. A contractor in Lomé buying equipment in Lyon doesn't have to worry about sudden currency collapses wiping out their margins.
Critics, however, view the peg as a brake on industrial development. Monetary policy in the zone isn't a carbon copy of Frankfurt, but the gravity is hard to escape. The BCEAO is an independent central bank with its own committee, yet it cannot ignore the ECB. If the euro's interest rates climb while West African rates stay low, capital tends to flee the region for better returns in Europe. To prevent this and protect their reserves, central bankers in West Africa often face intense pressure to raise interest rates in tandem, regardless of whether local businesses need cheaper credit.
The 2019 reforms and the road to the Eco
In December 2019, Côte d'Ivoire President Alassane Ouattara and French President Emmanuel Macron announced a major overhaul of the West African CFA franc. Under the treaty ratified in 2020, the BCEAO is no longer required to deposit its foreign exchange reserves with the French Treasury, and French representatives stepped down from the central bank's board and monetary policy committee.
The agreement kept two core pillars: the fixed rate of 655.957 per euro and the French Treasury's ultimate convertibility guarantee. Member states also announced their intention to rename the currency the "Eco", positioning it as a stepping stone toward a broader currency for the entire 15-member Economic Community of West African States (ECOWAS).

Realizing that broader union has proved difficult. Non-CFA members like Nigeria and Ghana voiced skepticism about launching a shared currency backed by a European treasury guarantee. Divergent inflation rates and fiscal deficits across the region have repeatedly delayed the full rollout of the Eco. For now, the CFA franc remains exactly what it's been for decades: an ironclad peg to the European continent, prized for stability by some and criticized as an economic relic by others.
Frequently asked questions
What is the official exchange rate between the euro and the CFA franc?
The West African CFA franc (XOF) is fixed to the euro at exactly 655.957 CFA francs per 1 euro (displayed on market feeds as 655.96). This parity was established when the euro replaced the French franc in 1999.
Which countries use the West African CFA franc?
Eight independent countries use the currency: Benin, Burkina Faso, Côte d'Ivoire, Guinea-Bissau, Mali, Niger, Senegal, and Togo. They form the West African Economic and Monetary Union (UEMOA), with monetary policy directed by the BCEAO in Dakar.
Why does the CFA franc fluctuate against the US dollar?
Because the CFA franc is permanently pegged to the euro, its exchange rate against other currencies mirrors the euro. When the euro gains or drops against the US dollar on international markets, the CFA franc automatically shifts against the dollar by the same proportion.
What changed with the 2019 CFA franc reform?
The reform removed French representatives from the BCEAO's governing bodies and ended the rule requiring the central bank to keep foreign exchange reserves at the French Treasury. France continues to provide a convertibility guarantee, and the peg to the euro remains unchanged.
What is the Eco currency?
The Eco is the planned name for the currency intended to succeed the CFA franc. While UEMOA nations agreed to rename their euro-pegged currency the Eco, the broader plan by the 15-member ECOWAS bloc to launch a shared, floating regional currency remains stalled by fiscal divergence.
